<p style="margin-left: 40px;"><strong>Rule 1</strong>: If you're simply using the greater than ($>$) or less than ($<$) signs, the line should be <u>dotted</u>.</p>
<p style="margin-left: 40px;"><strong>Rule 2</strong>: If you're using the greater than or equal ($\geq$) or less than or equal ($\leq$) signs, the line should be <u>solid</u>.</p>
<p><strong><span style="color:#8e44ad;">For Equations with both $x$ and $y$ present:</span></strong></p>
<p style="margin-left: 40px;"><strong>Rule 3</strong>: If you see a $y>mx+b$ or $y \geq mx + b$, shade ABOVE the line.</p>
<p style="margin-left: 40px;"><strong>Rule 4</strong>: If you see a $y<mx+b$ or $y \leq mx + b$, shade BELOW the line.</p>
<p><strong><span style="color:#8e44ad;">For equations with only one variable present, either $x$ or $y$:</span></strong></p>
<p style="margin-left: 40px;"><strong>Rule 5</strong>: If you have an equation with only one variable, say $x < 5$, shade to the LEFT of the line. If you see $x > 5$, shade to the RIGHT of the line.</p>
<p style="margin-left: 40px;"><strong>Rule 6</strong>: If you have an equation with only one variable, say $y < 5$, shade BELOW the line. If you see $y>5$, shade ABOVE the line.</p>
